No, they didn't. You can't install debian without systemd. They _said_ they let you switch, but they don't. People did not fork an entire distro just because they didn't like to press "option B" instead of "option A".
> If this is "essentially forcing" the use of systemd, then what possible choice would have counted as not forcing it other than making sysv the default?
1. Not having packages depend on systemd.
2. Bringing up a prompt/dialog during installation to make a choice of whether or not to use it.

Because Devuan is just Debian with some tiny changes and a different choice of packages. And of course, the infrastructure of a project - website, forum, IRC, download servers, etc. So of course most developers aren't concerned with that, they just provide/maintain upstream packages.

I didn't know about this aspect, thank you.
